ARP 104-6008 Cylinder Head Stud Kit

The ARP 104-6008 is a premium cylinder head stud kit engineered for high-performance and racing applications. ARP (Automotive Racing Products) is the industry leader in precision fastener technology, and this stud kit is manufactured to exceed OEM standards in both strength and reliability.

ARP head studs provide a significant advantage over conventional bolts by applying more accurate and consistent clamping force to the head gasket. Because studs remain stationary during torquing, the twisting stress is eliminated, resulting in a more uniform clamp load and improved head gasket sealing — critical in high-boost, nitrous, or high-compression builds.

Key Features:

• Manufactured from premium ARP 8740 chromoly steel or ARP2000 alloy (verify series for specific material)
• Heat-treated and precision centerless ground for consistent diameter and straightness
• Black oxide or polished finish for corrosion resistance
• Rolled threads for superior fatigue strength compared to cut threads
• Includes heavy-duty 2H nuts and hardened parallel washers
• Provides superior clamping force over OEM head bolts
• Designed for repeated installation without loss of integrity

ARP fasteners are made in the USA and trusted by professional engine builders, drag racers, and performance enthusiasts worldwide. Each kit includes all necessary studs, nuts, and washers for a complete installation.
